SAGINAW, MI — Using tips from social media and Crime Stoppers, Saginaw police on Thursday, Oct. 24, arrested the Saginaw woman charged with murder in connection with the June homicide of Randell Harris.

After receiving tips from Facebook and through the anonymous phone service, police Thursday afternoon arrested Tierra M. Washington at a house on Athens on the city's northeast side, said Saginaw Police Detective Sgt. Reggie Williams.

“It's great,” Williams said of the arrest. “It's showing that we're consistently using social media and consistently trying to motivate people to call in and give us tips. It's working, and we're very pleased with that.”

Saginaw County District Judge A.T. Frank on Friday morning arraigned Washington and ordered her jailed without bond pending a Nov. 7 preliminary hearing before District Judge Kyle Higgs Tarrant.

A 33-year-old man testified that he watched Moore, also known as “Nark,” fire a black semi-automatic handgun multiple times into the backyard.

The witness, whose name The Saginaw News is not reporting at police request, testified that Washington walked into the backyard, stayed for several seconds and then ran back to the front of the house and told Moore, “Yeah, he's back there.” Seconds later, Moore ran up the driveway and fired the shots, the witness testified.

The testimony showed that Harris and Washington, also known as “Tee Tee,” often had sex and that their relationship soured when Harris accused Washington of stealing Oxycontin from him two days before the homicide. A relative of Andrews testified that about an hour before the homicide, Washington called him crying and mumbling. In the background, the man testified, he could hear an angry man threatening to “(expletive) us up.”

In addition to the murder and conspiracy charges, which both carry mandatory sentences of life in prison without the possibility of parole, Washington is charged with carrying a dangerous weapon with unlawful intent and three counts of possessing a firearm during the commission of a felony.

Moore, who last lived at 420 Birch, remains jailed without bond, while Andrews remains jailed on a $750,000 bond. Their trial date before Saginaw County Circuit Judge Janet M. Boes was pending.
